Optimization of the E×B method for studying the charge composition of ions in the plasma jet of Hall effect thrusters [PDF]

open access: yesОмский научный вестник: Серия "Авиационно-ракетное и энергетическое машиностроение"
Electric propulsion rocket engines are widely used on board modern spacecraft. To ensure the efficient use of such engines, it is important to diagnose the plasma plume of the engine.

Numerical Aspects of Particle-in-Cell Simulations for Plasma-Motion Modeling of Electric Thrusters

open access: yesAerospace, 2021
The present work is focused on a detailed description of an in-house, particle-in-cell code developed by the authors, whose main aim is to perform highly accurate plasma simulations on an off-the-shelf computing platform in a relatively short ...

3D simulation of a Hall-effect thuster near plume with a central cathode

open access: yes, 2021
Raw simulation data of the near plume of an SPT-100 Hall Effect thruster, obtained using the 3D code "EP2PLUS". This makes use of a hybrid particle-in-cell/fluid (PIC/fluid) formulation, and is here used to assess the 3D effects of the neutralizer ...

Fast Camera Analysis of Plasma Instabilities in Hall Effect Thrusters Using a POD Method under Different Operating Regimes

open access: yesAtmosphere, 2020
Even after half a century of development, many phenomena in Hall Effect Thrusters are still not well-understood. While numerical studies are now widely used to study this highly non-linear system, experimental diagnostics are needed to validate their ...

3D simulation of a Hall-effect thuster near plume with a lateral boundary cathode

open access: yes, 2021
Raw simulation data of the near plume of an SPT-100 Hall Effect thruster, obtained using the 3D code "EP2PLUS". This makes use of a hybrid particle-in-cell/fluid (PIC/fluid) formulation, and is here used to assess the 3D effects of the neutralizer ...

Advanced laboratory for testing plasma thrusters and Hall thruster measurement campaign

open access: yesNukleonika, 2016
Plasma engines are used for space propulsion as an alternative to chemical thrusters. Due to the high exhaust velocity of the propellant, they are more efficient for long-distance interplanetary space missions than their conventional counterparts.

High Fidelity Multi-Objective Design Optimization of a Downscaled Cusped Field Thruster

open access: yesAerospace, 2017
The Cusped Field Thruster (CFT) concept has demonstrated significantly improved performance over the Hall Effect Thruster and the Gridded Ion Thruster; however, little is understood about the complexities of the interactions and interdependencies of the ...
